'Do You Not Know' in the Bible

Do you [who worship idols] not know? Have you not heard?Has it not been told to you from the beginning?Have you not understood from the foundations of the earth [the omnipotence of God and the stupidity of bowing to idols]?

Do you not know?Have you not heard?Yahweh is the everlasting God,the Creator of the whole earth.He never grows faint or weary;there is no limit to His understanding.

Behold, I will do a new thing. It springs forth now. Do you not know it? I will even make a way in the wilderness, and rivers in the desert.
